Damp or musty smell
A damp or musty smell is caused when dust in the cyclone has come into contact with water.
It may not be a direct contact with water, for example when vacuuming pet hair that is slightly damp, this moisture will combine with the dust in the cyclone causing the smell.
Additionally the smell may occur if the filter goes back into the machine wet.
Only the filter can be washed, the bin can be cleaned with a damp cloth only, and both must be completely dry before being refitted to the machine.
Clean the bin
To ensure your machine continues to clean effectively, the clear bin must be emptied as soon as the dust reaches the MAX mark.
Push the button on the Main body of the machine downwards to release dust directly into a dustbin.
Clean the clear bin with a damp cloth only.
WARNING: Do not use detergents, polishes or air fresheners to clean the clear bin. Do not put the clear bin in a dishwasher.
Refit the bin
Ensure the bin is completely dry before replacing. To replace the bin, push it up and in to the Main body of the machine until it clicks in to place.

Damp or musty smell still present
Under normal use, any unpleasant smell can only be caused by something the machine has picked up. Please select pick up issues to carry out checks.
